Product Overview

Welding neck flange refers to a flange with a tapered neck and butt-welded to the cylinder or pipe. It is an integral flange. Due to the transition structure of the tapered neck and the butt welding connection, the strength and rigidity of the flange are enhanced, and the sealing is better than plate flange.
